Joanne Kathleen Rowling wrote seven Harry Potter novels from
1995 to 2006. These seven novels were made into eight major motion
pictures making Rowling the wealthiest woman in Great Britain this side of
Elizabeth II. Rowling is the first speculative fiction author to receive
the full Mad treatment since Mad #18 when Lewis Carroll's Alice in
Wonderland was the subject of an seven-page Kurtzman parody.
Writer Desmond Devlin provided fourteen pages of text that were condensed into
seven
pages plus the James Warhola splash ("Harry Plodder and the Kidney Stone").
Devlin concluded that much of the Harry Potter fantasy theme was borrowed from
Superman, Cinderella, and Star Wars.
However, I will give Rowling a pass. There are only so many themes
available to syfy writers and she created a magical world that has already
become a literary classic. [JAM 11/13/13]

The Mad editors became somewhat confused on page ten of "7th Heaving".
In the second panel, "Loopy" seems to be talking to herself.
